The big difference between those years was the location of the power steering hose reservoir. Is yours up near the firewall, on the driver's side, aft of the windshield washer bottle?
Or is it down towards the front, hanging off two bolts over the top of the radiator?
If you have the latter (the bottle is a big white one, or greasy light yello by this time) then you can buy the 88-89 hoses.
Truth to be told, it's better if you just had a shop custom make one for you. Buy a better quality hose and have them put in better quality hose ends. The Alfa ones are OK but WILL leak over time. I like cleaner engine bays than dirty/oily ones

but that's just me...
